Greetings,
I rebased the project to the 2017.10.26 jdk10/hs PIT snapshot.
Here are the updated webrevs:
Here's the mq comment for the change:
Rebase to 2017.10.25 PIT snapshot.
Here is the full webrev:

And here is the delta webrev:

I ran the above bits throught Mach5 tier[1-5] testing over the holiday
weekend. Didn't see any issues in a quick look. Going to take a closer
look today.
We welcome comments, suggestions and feedback.

Greetings,
Resolving one of the code review comments (from both Stefan K and Coleen)
on jdk10-04-full required quite a few changes so it is being done as a
standalone patch and corresponding webrevs:

Greetings,
We have a (eXtra Large) fix for the following bug:
8167108 inconsistent handling of SR_lock can lead to crashes
https://bugs.openjdk.java.net/browse/JDK-8167108
This fix adds a Safe Memory Reclamation (SMR) mechanism based on
Hazard Pointers to manage JavaThread lifecycle.
Here's a PDF for the internal wiki that we've been using to describe
and track the work on this project:
http://cr.openjdk.java.net/~dcubed/8167108-webrev/SMR_and_JavaThread_Lifecycle-JDK10-04.pdf
Dan has noticed that the indenting is wrong in some of the code quotes
in the PDF that are not present in the internal wiki. We don't have a
solution for that problem yet.
Here's the webrev for current JDK10 version of this fix:
http://cr.openjdk.java.net/~dcubed/8167108-webrev/jdk10-04-full
This fix has been run through many rounds of JPRT and Mach5 tier[2-5]
testing, additional stress testing on Dan's Solaris X64 server, and
additional testing on Erik and Robbin's machines.
We welcome comments, suggestions and feedback.
